Great analysis of Google's purchase of Nest (a maker of hi-tech thermostats), which will make it easier to advertise energy efficiency to Nest users (win-win, in the tradition of google ads; Facebook would probably post your stats in public)

H/T to RM* I love free-trade, but the "offshoring pollution" hypothesis (production is moved to a country with lax environmental regulations while consumption continues as normal) is a weakness when poorer governments do not/cannot care about pollution to their citizens or neighbors.**
